Lopez still unsure about Idol

Steven Tyler says Jennifer Lopez is still unsure if she will return to American Idol. The rock star has spoken to his fellow judge and she told him she didn't know whether to take part in the TV show for a third year running. There has been speculation about the pop star's involvement and a potential replacement for some time, with UK singer Cheryl Cole being suggested as a potential successor. "I asked her the other night if she's coming back and she said she doesn't know," Steven was quoted as saying by British newspaper The Sun. Jennifer is certainly keeping busy with a number of projects that could conflict with the intense filming schedule of American Idol. As well as preparing to tour with Enrique Iglesias and Wisin Y Yandel this summer and a rumoured reality TV show about boyfriend Caspar Smart's work with her dancers in the pipeline, the mother-of-two is still working on talent show ¡Q'Viva! Jennifer earned cheers from the audience when she walked on stage holding hands with her estranged husband and co-host Marc Anthony over the weekend. The couple separated 11 months ago but kept things amicable for the sake of business as they shared a hug on stage to rousing applause from onlookers.
